This app destroys my conversion rate. Due to this app customers can't reach Cart and checkout pages...

You have misunderstood what the app does!!! 😅 😅 😅
Your theme has a cart drawer that needs to be turned off! (see your video)

We have 1000's of stores that use the app perfectly.
Please reach out to the support team if you don't know how to do this.

1000% guarantee the problem can be easily fixed and it's only related to your theme.

B&B Labs Cosmeceuticals

This apps is powerful, not to mention that the live support, Ty is super fast, friendly, and efficient.


Highly recommend this app for higher conversion rates. Customer service is great and I usually have a response for any queries within minutes. Definitely recommend if you like a place for your cart upsells and campaigns to be all-in-one.

I can't speak more highly of the team at Monster Upsells, especially Ty! He was so helpful, AND SPEEDY, in getting my customised cart up and running and I'm really excited to see how it improves my AOV!

Es muy fácil de configurar y el servicio al cliente es una joya. Sin duda recomiendo la app. Shootout to Ty for helping us!

Minx Bronzing and Cosmetics

Ty & the team at Monster Upsells go above & beyond to assist with intergration. We had a few issues as we are B2B & B2C - however it was an easy fix with a couple of the apps talking to each other. Monster Apps after sales support is like nothing that we have experienced before & we have had our Shopify store for 7 years
We just need them to come out with more apps :)
